项目摘要
This collaborative project, involving Dartmouth College, the University of Alaska Fairbanks, and SRI, will explore and develop a new data infrastructure through the system-science use of a Swarm-over-Poker 2023 auroral observational campaign. The team will create new and powerful combined data products from this heterogeneous, distributed, multipoint data set and develop a data-sharing platform to share the derived heterogeneous data products and algorithms with the community. These data are interwoven into new, featurized data products and maps for both ionospheric model ingestion and ML studies. These products and tools will enable studies addressing science questions such as how and to what extent the auroral environment context (activity level, local time, latitude) controls the specifics of pre-midnight arc-scale auroral activity and coupling. This is timely as our community moves toward true system-science efforts that require a diversity of data to greatly advance our understanding of auroral generation and electrodynamics. The novelty of this project is that it will demonstrate the design of a research infrastructure for sharing and archiving derived data products from heterogeneous sources to enable new science for cross-scale cross-region coupling auroral studies. Graduate and undergraduate students will be supported by this project. The students exposed to this project will learn to work with heterogeneous and “multifaceted” CEDAR system science, interweaving multiply-distributed data with featurization tools, and with modelling, as needed for cross-scale cross-region coupling auroral studies. The project will host a series of virtual community discussions to engage with the broader geospace community.Swarm-over-Poker 2023 provided the opportunity to collect in situ ionospheric current and flow data from the ESA Swarm spacecraft, during nightly conjunctions with Poker Flat Research Range (PFRR), Alaska, from mid-February through the end of March 2023. The PFRR data include filtered auroral imagery, Poker Flat Incoherent Scatter Radar (PFISR) radar data, ground magnetometry, and additional instrumentation. The Swarm in situ data include thermal ion plasma flow data and field-aligned current data. From this heterogeneous, distributed, multipoint data set, the team will create new and powerful data products to address auroral system science by data-driving ionospheric models. The three science objectives are (1) an auroral system-science study of 2- way arc-scale vs regional-scale coupling for nightside auroral arcs using the winter 2023 Swarm-over-Poker campaign dataset. (2) Generation of tools for, and the data products of, ionospheric model-absorbable imagery-derived and imagery-guided heterogeneous data products for this campaign, and for shared public use. (3) Using this CEDAR-science driven study as a testbed for designing a new data infrastructure for using and sharing heterogeneously-derived CEDAR-science data products. Specific science questions to be addressed are (1) How, and how much, does the regional auroral environment constrain the details of specific arc-scale features? (2) What is the effect on the regional auroral environment, from arc-scale event signatures?This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
这个合作项目涉及达特茅斯学院,阿拉斯加大学费尔班克斯和SRI,将通过系统科学使用Swarm-over-Poker 2023极光观测活动来探索和开发新的数据基础设施。 该团队将从这个异构、分布式、多点数据集中创建新的、强大的组合数据产品,并开发一个数据共享平台,与社区共享衍生的异构数据产品和算法。 这些数据交织成新的,功能化的数据产品和电离层模型摄取和ML研究的地图。 这些产品和工具将使研究能够解决科学问题,例如极光环境背景(活动水平,当地时间,纬度)如何以及在多大程度上控制午夜前弧尺度极光活动和耦合的细节。这是及时的,因为我们的社会走向真正的系统科学的努力,需要多样化的数据,大大提高我们的极光生成和电动力学的理解。该项目的新颖之处在于,它将展示一个研究基础设施的设计,用于共享和存档从不同来源获得的数据产品,以使新的科学能够进行跨尺度跨区域耦合极光研究。 研究生和本科生将得到该项目的支持。 接触这个项目的学生将学习使用异构和“多方面”CEDAR系统科学,将多个分布式数据与特征化工具交织在一起,并根据跨尺度跨区域耦合极光研究的需要进行建模。 该项目将举办一系列虚拟社区讨论,以与更广泛的地球空间社区进行互动。Swarm-over-Poker 2023提供了从欧空局Swarm航天器收集现场电离层电流和流动数据的机会,从2023年2月中旬到3月底,在与阿拉斯加扑克平地研究范围(PFRR)的夜间连接期间。PFRR数据包括过滤极光图像,扑克牌平面非相干散射雷达(PFISR)雷达数据,地面磁力测量和其他仪器。Swarm现场数据包括热离子等离子体流数据和场对准电流数据。 从这个异构的,分布式的,多点的数据集,该团队将创建新的和强大的数据产品,以解决极光系统科学的数据驱动电离层模型。 这三个科学目标是:(1)使用2023年冬季Swarm-over-Poker活动数据集对夜侧极光弧的双向弧尺度与区域尺度耦合进行极光系统科学研究。(2)为电离层模型可吸收的图像衍生和图像引导的异构数据产品生成工具和数据产品,供这一活动和公众共享使用。(3)使用这个CEDAR科学驱动的研究作为一个试验平台,设计一个新的数据基础设施,使用和共享异构衍生的CEDAR科学数据产品。 要解决的具体科学问题是(1)区域极光环境如何以及在多大程度上限制了特定弧尺度特征的细节?(2)弧尺度事件特征对区域极光环境的影响是什么?该奖项反映了NSF的法定使命,并被认为是值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估的支持。
